Software stroke limit function
In the "software stroke limit function" the address established by a machine home position return is used to set the upper and
lower limits of the moveable range of the workpiece. Movement commands issued to addresses outside that setting range will
not be executed.
In the Simple Motion module, the "feed current value" and "machine feed value" are used as the addresses indicating the
current position. However, in the "software stroke limit function", the address used to carry out the limit check is designated in
the "[Pr.14] Software stroke limit selection". Refer to the following for details on the "feed current value" and "machine feed
value".
Page 59 Confirming the current value
The upper and lower limits of the moveable range of the workpiece are set in "[Pr.12] Software stroke limit upper limit value"/
"[Pr.13] Software stroke limit lower limit value".
Differences in the moveable range
The following drawing shows the moveable range of the workpiece when the software stroke limit function is used.

The following drawing shows the differences in the operation when "[Md.20] Feed current value" and "[Md.21] Machine feed
value" are used in the moveable range limit check.
■Conditions
Assume the current stop position is 2000, and the upper stroke limit is set to 5000.
